Hello Ben,
You need to install luci package and start the luci service on the node, preferably outside of the cluster nodes and ricci package on all the cluster nodes. Start the ricci service on all the cluster nodes, provide ricci password.
When you start the luci service, you will be given a web url which will help you to configure cluster and many more operations of the cluster as well it will help you to monitor them.
For more details, please see

Thank you

Hello Ben,
Red Hat does not provide / recommend any third party tool to monitor / configure cluster via web interface.
If the cluster node having luci goes down, as you said command line is the only option if you do not wish to use the third system.
Thank you

If you are on RHEL 6, the High Availability stack does support a number of different snmp traps via Foghorn:

As mentioned earlier we don't specifically have any 3rd party monitoring tools that we recommend, but if you already have monitoring tools that are able to use snmp, you can hook it up to your cluster this way.
Hope that helps.

Do you mean how to configure SNMP on the cluster side? Or in Nagios? For the cluster, see the link I posted in my previous comment. If you meant Nagios, I'm afraid I won't be of much help there.

You need to install the snmp cluster tools rpm: cluster-snmp-0.16.2-14.el6.x86_64
Also, add the following line to your /etc/snmp/snmpd.conf file:
dlmod RedHatCluster /usr/lib64/cluster-snmp/libClusterMonitorSnmp.so
Once you install the cluster-snmp package, the mib can be found here:
/usr/share/snmp/mibs/REDHAT-CLUSTER-MIB
Hope that helps

Why did you install luci on a cluster node?
Do not you have a small management server in the same VLAN(s)?
Is it best practise to run your management tools outside your cluster.
The way we monitor some Red Hat clusters, using Nagios and interprete the output of clustat.
Kind regards,
